Abstract: A method of determining the performance characteristics of an athlete includes the steps of defining a two-dimensional graph having a horizontal axis and a vertical axis, and plotting at least four points on the two-dimensional graph to form a rectangular performance grid. The points have coordinates (x,y) which represent individual performance statistics of the athlete. The performance characteristics of the athlete are determined by the horizontal and vertical position of the grid on the graph, and the height, width and shape of the grid. The two-dimensional performance grid simultaneously displays multiple performance statistic of the athlete and allows the viewer to simultaneously analyze multiple performance characteristics without the need to individually compare and analyze burdensome statistical numbers. Two or more performance grids are overlayed on a single graph in order to determine and compare the performance characteristics of two or more athletes.
